Overseeding and Crabgrass preemergent
We're now in April in New England and next week my lawn guy will be doing his power raking as part of his spring cleanup.
My question is this: I would like to lay down some perennial ryegrass overseed as my lawn was thin last year.
I have a contract with a lawn service and they are set to apply their step 1 fertilizer which has crabgrass preventer. I asked if the crabgress preventer will kill my new seeds, and they said I should be OK, as long as my new ryegrass seed has had two weeks to germinate...Is this right?
Obviously, I don't want to lay down a bunch new seed today, and have it germinate, only to have my pre-emergent laid down two weeks later and kill it.
